Installation
Installation – Microsoft Office 2021 Standard - For 3 PCs
- Please uninstall all old Office versions from your computer before installing the new Office package. You can find and uninstall these in the settings under Apps. If necessary, download the Microsoft tool for simple error correction to ensure that all old Office versions are completely uninstalled. Microsoft provides precise instructions here on how to uninstall all old Office versions. This is particularly important if you previously used Microsoft 365.
- Download the disk image file.
- Install the software by double-clicking on the disk image file and proceed by double-clicking on "start" or "RunMe". You may need to start the file by right-clicking on it and selecting "Run as administrator".
- Once the installation is complete, you can enter the key. To do this, open Word and click on "File" in the top left corner. You will now find the sub-item "Account" here. On the right side of the menu that opens, you will find "Enter product key" or "Change license". Please enter our key here.
If you encounter further problems with the installation or activation, please write to us. Simply use our contact form and it is best to attach a screenshot of the error message. We are happy to help you.

Microsoft lists 13 October 2026 as the end of support for Office LTSC 2021. Consider this when buying and compare Office 2024 where appropriate.
